| Abstract: | Non-linear differential equations of the damping orifices and channels and the method of computer solutions for determination of the configuration dimensions are discussed in this paper.The preloading pressure gradient, turbulence, shock pressure of flow-distribution and their changes with the design parameters for different types of damping orifices and channels are obtained by solving the non-linear differential equations. In order to obtain low-noise performance, a optimal design basis is, hence, presented by comparing and analyzing above mentioned results. |
